'Knew' in the Bible

I will make him know that I am about to judge his household forever because of the iniquity that he knew, for his sons [were] bringing curses on themselves, but he did not rebuke them.

{And when} all who knew him {formerly} saw that he prophesied with prophets, the people said to one another, "What [is] this [that] has happened to the son of Kish? [Is] Saul also among the prophets?"

Then Saul hurled his spear at him to kill him. So Jonathan knew {that his father had decided} to kill David.

But the boy did not know anything [about this]; only Jonathan and David knew the matter.

So the king said to the runners [who were] stationed around him, "Turn and kill the priests of Yahweh, because {they also support David} and because they knew that he was fleeing and {did not disclose it to me}." But the servants of the king [were] not willing to raise their hand to attack the priests of Yahweh.

Then David said to Abiathar, "I knew on that day that Doeg the Edomite was there, that he would certainly tell Saul. {I am responsible for the deaths of all your father's household}!

So David took the spear and the jar of water from [near] Saul's head, and they went [away]. {No one saw, no one knew, and no one awakened}, for all of them [were] sleeping because a deep sleep of Yahweh had fallen upon them.
